HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 513, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 804, 513, 497 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 804, 513, 497 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 804, 513, 497 is 1.
HCF(804, 513, 497) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 804, 513, 497 is 1.
Step 1: Since 804 > 513, we apply the division lemma to 804 and 513, to get
804 = 513 x 1 + 291
Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 291 and 513, to get
513 = 291 x 1 + 222
Step 3: We consider the new divisor 291 and the new remainder 222, and apply the division lemma to get
291 = 222 x 1 + 69
We consider the new divisor 222 and the new remainder 69,and apply the division lemma to get
222 = 69 x 3 + 15
We consider the new divisor 69 and the new remainder 15,and apply the division lemma to get
69 = 15 x 4 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 804 and 513 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(69,15) = HCF(222,69) = HCF(291,222) = HCF(513,291) = HCF(804,513) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 497 > 3, we apply the division lemma to 497 and 3, to get
497 = 3 x 165 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 497 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(497,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
